PATENT ori-fics ror EUGENE, oianeon sivowrtow Application fiieafiviay i7,'

a tractor or' other propelling mechanism with l rotatable blades orf shovels disposed' at the forward open side ofthe 'casing forv cutting n th'roughfo'neof the sliovelsupporting shafts ice and snow and for gathering the salmeinto the casing for discharge'bya fanblower through a conduit to a distant point.

VA further object of the yinvention is to provide a snow plow of the above'type wherein the rotatable shovel [andfan blower are operatively engaged withthepower plant of the tractor with means interposed therebetween'ffor varying the speed of rotation of the'fan and shovel. l

Another important object ofthe invention is to: provide a snow plow as before Vset forth wherein the rotatable shovels are supported on vertical shafts journaled inthe forward open sider of the casing, the shovels travelling in a pathforwardly of the casing for breaking the snow and i'c'e before the casing Amoves vinto Contact therewithl for the purpose of offering-the least resistance possible' to the forward travel of theapparatus.

' A still further object of this invention is to lprovide 'a snow kplow that is vertically line permitting transportation ofthe inachine when outof use kand also compensating for unevenness in line' of travel as well as escaping abutments such as stones andthe like. Y l

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawshovel; i

The' snow plow comprises a shovel casing located-forward of'andattached to a propelling device such'asa tractor in ka manner to of one of the shafts'with the shovel arms vpi vi be later described, the casing being of trapezoid'al formation in plan view and comprising rearwardly converging top and bottom ywalls land 2,- rearwardly 'converging side walls 3 and a rear wall 4, all of said walls beings'ecuredtogether attheir meetinge'dges in any suitabley manner, suoli as by angle irons 5 that are rivetedthereto as at the casing being completely' open at `its'forward side-at 7 as 'jshown' inlFigures 1 and 2. A front sh'oe or runner' barfS*of the lform best illustrated 1n Figure 3 extendsacross the forward edge of the 'lowerlwall 2 of thevcasing and carries runner arms 9. A bar orl rod 11 is riveted or otherwise secured as at 12 to the side walls 3 ofthe casing and extend rearwardly for pivotalattachment to a tractor, not shown. Control lines inthe form of cables or the like are shown at 13 are attached as at 14 at their forwardends to the forward upper corners of the side walls 3 and are controlled from the i tractor for raising and lowering the casing relatively to the ground line 15 so that Vthe vcasing-mayl be elevated when the plow is being transported from one place to another and also to escape abutments such as stones and the like,

A plurality of vertical shafts 17 are ournaled across the front opening 7 of the casing, the same being supported at the lower ends in suitable bearings carriedby .the bottom Wall 2 of thecasing while-the 'upper ends thereof are journaled in al cross bar 16 supported at its ends on the side walls 3 at points spaced below the top wall 1, theshafts .17 being equidistantly spaced from each other and While four of such shafts are illustrated, it is to be understood thatany preferred number may be employed. As showninoreclearly inF-igures 2,4jand 5, each-shaft17has a plu- -ralityof spaced disky blocks 18 `keyed thereon as at 19 Withtheblockslof adjacent shafts being located in` different horizontal planes. A .plurality of bladesV orshovel arms-20 of ,"curvedfformation-in planview are pivotally .mounted attheir inner jends as at 21` upon the `uppergside of thefdisk block 18, j 3referably four shovel arms 20 being associated .with teach-block, the shovel arms on adjacent shafts overlapping each other in verticallyspaced ,relation as shown in Figure-2. The shafts 17 aredisposed with .relation to the forward side `ofthe casingsothat the shovel arms 2O `project beyond the casing-as illustrated in Figures 1 and 2 for-breaking down a bank of ice and snow forwardly of the casing; K

A The operatingrmechanism `for `rotating the shafts 17 includes a drive shaft QQ-leading @from theL power plant of thetractor and eX- Y tondi-ng into the transmission housing 23, the

A fan blower or wheel comprising blade arms 39 is fixed to the shaft 38 adjacent the casing wall 4 and is adapted to force snow and ice gathered in the casing by the shovel arms 2O through an opening in the-top Wall l into the discharge conduit 4() outleting at a distant point. The speed of rotation ofthe :fan wheel`39and gearniechanism in the transmission housing 23 may be varied proportionately to the amount of snow .and ice collected inthe casing.

From the above detailed description of the invention, it is believed that the construction and operation will at once be apparent, it be- 'ing noted tl'i'at'tliei'snow plow 1s positioned forwardly of a propelling device such'as a tractor and supported Aon, the tractor` by the rearwardly extending `bars 11. The cables 13 lare operated for raising and lowering the casing as previously described, While the shovel arms 20 projecting forwardly of the casing as illustrated in 'Figures 1 and 3, break down ai bank of ice and snow preparatory to Contact therewith ofthe jcasing so that forward movement-of-thesnow plow, issubstantially unimpeided.
